Jenbacher BackgroundA leading manufacturer of gas-fueled

reciprocating engines for power generation.

• Acquired by GE in May ’03…100% gas-fueled recips

• Manufacturing/HQ in Jenbach, Austria

• Employees: 1,800 total; 1,400 in Austria

• Power range from 0.25MW to 4MW, 4 platforms / 11 products

• Fuel flexibility: Natural gas or a variety of renewable or alternative gases (e.g., landfill gas, biogas, coal mine gas)

• Plant configurations: Generator sets, cogeneration systems, container solutions

Important Gas Properties

Heating Value Calorific value and thermal value indicate the energy content of a gas. The former can be differentiated from the later only through the heat of vaporization of the water resulting from combustion, the water is in liquid form after it has already liberated its condensation heat.

Methane NumberDeterminant parameter for knocking resistance of a gas. It is comparable to the Octane Number of gasoline and indicates the percentage methane volume ratio of a methane-hydrogen mixture which, in a test engine and under controlled conditions, indicates the same knocking resistance as the gas to be tested.

Laminar Flame SpeedLaminar flame speed is the speed at which the oxidation takes place.

Combustibility depends on the combination of composition and NOT on the heating value of the gas

Characteristics of Flare gas

Gas composition: main constituents• Methane CH4 40 - 90%• Ethane C2H6 2 - 20%• Propane C3H8 1 - 15%• Butane C4H10 1 - 10%• Carbondioxid CO2 1 – 40%• Methane numbers: 30 - 65• Lower Heating Value [kWh/Nm³]: 11 - 20• In case of high contents of H2S, desulphurization

is needed

Associated gas varies in composition & flow over time» High flexibility in operation and control necessary

LEANOX® - Lean-burn combustion control

•Sensors in non critical measurement ranges (pressure, temperature, deposits...)

•Reliable and durable compliance with exhaust emission limit at changing operational conditions (fuel gas compositions...)

•Controlled combustion and subsequently controlled stress of various components (valves, cylinder heads, spark plugs...)


03.-05.03.2010

Main requirements for applications in the oil and gas industryOperation with associated petroleum gas (flare gas)• Fuel flexibility• Stable island operation• Operation at low Methane numbers

Operation in hazardous environment• Gas engines can not be operated in ATEX zones 0-2• Enclosures must be built accordingly• Ventilation systems to ensure CH4 dilution• Spark arrestors in exhaust gas systems

Features of Jenbacher container-concept

•Pressurized ventilation => good dilution in case of gas leakage (safety concept)

•All components on the container roof =>small footprint

•Separated control room

•Optimisation of air flow for best cooling results

•Minimal number of interfaces

•Sound attenuation levels of 65 dB(A) and lower possible

•Best accessibility for maintenance via double doors

•Special versions for full heat recovery (cogeneration) available

Power plant output rangeProduct line 2010 (50Hz) – Natural gas NOx ≤ 500 mg/m³N

Electrical Efficiency up to 45% Thermal Efficiency up to 50%

Additional benefits with multiple engine approach- High fuel efficiency: engines constantly running at nominal load and efficiency

- Availability and reliability: stable electrical output

- Flexibility: scheduled maintenance in sequence
